As shown in this, the three-dimensional character for the sign according to the present invention is attached to the dial 10, the inner character member 20 which is attached to the inside of the lower surface of the dial 10, the outer surface of the lower surface of the dial 10 The outer character member 30, the upper LED module 40 provided in the inner lower portion of the inner character member 20, the lower LED module 50 is provided on the lower surface of the dial 10, and the inner The upper epoxy resin layer 60 formed in the inside of the character member 20, and the lower epoxy resin layer 70 formed in the inside of the said outer character member 30 are included.

The dial 10 is provided in a plate shape of the letter shape and is cut into the same letter shape inside to form the inner letter hole 11, and serves to form a basic frame for forming a three-dimensional character for the sign. The inner letter hole 11 serves as a hole through which the light emitted by the upper LED module 40 is transmitted from the inside of the letter board 10 and at the same time the shape and attachment position of the inner letter member 20. It is easy to understand.

The outer character member 30 is attached to the lower surface of the dial 10 to surround the lower outer side of the dial 10 at the same height as the inner character member 20, and the inner character member 20 and Similarly, after bending the metal plate to produce a three-dimensional shape, it is preferable to form a welding plate attached to the lower surface of the letter board 10 along the outer periphery of the letter plate 10. Epoxy resin is to be filled in the lower surface.

The external character member 30 is made of a metal plate, but is not limited thereto, and may be manufactured using, for example, an acrylic plate or a synthetic resin plate, which is a rigid plate-shaped material capable of forming a predetermined frame.

 The upper LED module 40 is provided with a plurality along the inner lower portion of the inner character ball 11 toward the upper direction toward the inner side of the inner character member 20, and the light emitted by the supply of power, the inner character It is preferable that the lower surface of the member 20 is disposed on the upper surface of the blocking film in a state of being closed with a blocking film such as sheet paper, and installed on the inner lower part of the internal character member 20, and a printing for supplying a known LED and its power supply. It is composed of a circuit board, and emits light by the supply of power serves to irradiate light to the upper side of the internal character member 20.

That is, the upper LED module 40 is to irradiate light to the front of the three-dimensional character to display the character through the inner character hole 11 to the inside of the dial (10).

A plurality of the lower LED module 50 is mounted downward along the lower surface of the dial 10 and is emitted by the supply of power, between the internal character member 20 and the external character member 30. It is preferable to be installed in a downward direction along the center of the lower surface of the letter board 10, and is composed of a known LED and a printed circuit board for supplying power thereof to the lower side of the letter board 10 while emitting light by supplying power. It serves to irradiate light.

That is, the lower LED module 50 is to irradiate light to the back of the three-dimensional character to highlight the outer back side of the dial 10 so that the three-dimensional feeling of the dial 10 is significantly enhanced.

The upper epoxy resin layer 60 is formed by filling an opaque color epoxy resin inside the inner character member 20, the upper LED module 40 is installed inside the inner character member 20 While fixing the to form a light emitting block is to be expressed in three dimensions.

The upper epoxy resin layer 60 is formed by completely filling with an opaque and colored color epoxy resin, or filled with a transparent epoxy resin first to fix the upper LED module 40, the color epoxy resin on the upper side You can also fill in to express the color.

The lower epoxy resin layer 70 is formed by filling an opaque color epoxy resin between the inner character member 20 and the outer character member 30 to the lower surface of the dial 10, the inner character While fixing the lower LED module 50 installed on the lower surface of the dial 10 between the member 20 and the external character member 30, one light emitting block is formed to surround the lower surface of the dial 10. It is to enable light emission.

The lower epoxy resin layer 70 is formed by completely filling with an opaque and colored color epoxy resin, or by filling the transparent epoxy resin first and fixing the upper LED module 40 to the lower side of the color epoxy resin. You can also fill in to express the color.

The color of the upper epoxy resin layer 60 is more preferably different from the color of the lower epoxy resin layer 70. This is the front of the three-dimensional character (top surface as shown) of the lower LED module 50 in the state that the character is displayed in a specific color by the light emission of the upper LED module 40 through the inner character hole 11 By displaying different colors around the lower circumference of the dial 10 on the back (lower surface as shown) of the three-dimensional characters seen by light emission, the three-dimensional feeling and visibility of the three-dimensional characters are significantly improved.

In this way, the three-dimensional character is a useful invention that significantly increases the visibility and aesthetics while the three-dimensional effect of the three-dimensional character itself is significantly increased by the front emission and the bottom emission.

Figure 3 is a perspective view showing the installation state of the three-dimensional character for the sign according to the invention, Figure 4 is a schematic side cross-sectional view of FIG.

As shown in this, the three-dimensional characters are fixedly installed in a state separated from the front of the sign (SB) with a plurality of el-shaped bracket on the front of the sign (SB). When power is supplied in the installed state, the upper LED module 40 and the lower LED module 50 emit light, and light is radiated through the upper epoxy resin layer 60 and the lower epoxy resin layer 70. .

For example, if the upper epoxy resin layer 60 is formed of a red color, and the lower epoxy resin layer 70 is formed of a blue color, through the inner letter hole 11 of the dial (10) A red letter (T according to the illustrated example) is represented by the upper epoxy resin layer 60 while blue light is emitted to the lower epoxy resin layer 70 to the back of the dial 10. Is surveyed towards the front.

In this way, the light irradiated to the front of the sign (SB) is reflected by the sign (SB) to the outside of the dial 10, more specifically, to the outer periphery of the outer character member 30, The dial 10 improves the three-dimensional appearance.

In addition, an inner side of the internal character member 20 in which the upper epoxy resin layer 60 is formed is opened, and a part of the light irradiated to the front surface of the sign SB through the lower epoxy resin layer 70 is reflected. As the upper epoxy resin layer 60 is introduced into the upper epoxy resin layer 60, the upper epoxy resin layer 60 has a relatively higher illuminance or brightness than the lower epoxy resin layer 70.

That is, the upper epoxy resin layer 60 is a part of the light generated by the lower LED module 50 is also introduced as the light irradiated from the upper LED module 40 is directly projected to the front surface relative to the brightness or illuminance On the other hand, the light irradiated to the front surface of the signboard SB through the lower epoxy resin layer 70 is indirect light reflected by the signboard SB without being directly exposed to the outside and thus the upper epoxy resin layer ( Light having a lower brightness or illuminance than light passing through 60 is formed around the rear surface of the dial 10.

The three-dimensional characters viewed in this way display the characters with a relatively high illuminance light toward the front center and display the periphery of the dial 10 with light of low illuminance and soft light on the back of the dial 10. The three-dimensional feeling and visibility of this three-dimensional character of remarkably increases.

Figure 5 is a longitudinal cross-sectional view showing another embodiment of a three-dimensional character for a signboard according to the present invention.

As shown in the figure, the upper epoxy resin layer 60 of the three-dimensional character for the sign is preferably formed relatively lower than the dial (10). That is, as the upper epoxy resin layer 60 is formed lower than the dial 10, the letters provided in the inner letter hole 11 enter into the lower side of the dial 10 relatively, and the upper epoxy is seen. The three-dimensional feeling of the character represented by the resin layer 60 is improved more.

In addition, the outer character member 30 of the three-dimensional character for the sign further includes a plurality of light emitting holes 31 formed to penetrate horizontally around the lower end. The light emitting hole 31 is emitted by the lower LED module 50 and a part of the light passing through the lower epoxy resin layer 70 is emitted directly to the outer circumference of the outer character member 30 to the dial ( It is to make the back light emission of the three-dimensional characters seen around the periphery 10 more smooth and strong.

Figure 6 is a longitudinal cross-sectional view showing another embodiment of a three-dimensional character for a sign according to the present invention.

As shown in the figure, the three-dimensional character for the sign further includes a point light source prevention unit 80 is installed on the upper LED module 40. The point light source preventing unit 80 serves to prevent the formation of the point light source by scattering the light irradiated in the upper direction from the upper LED module 40.

Here, the point light source refers to light that is emitted from high light at a point and appears to be a point when viewed by the eye. The light source does not spread evenly in a light source having a high luminance light such as an LED to show glare. The source of the light source.

As described above, the upper LED module 40 is installed at the front of the signboard to display the letters to the outside. As the plurality of LED modules 40 are installed in a state in which the plurality of LEDs are arranged inside the letter member 20, the light emitted through the same is evenly distributed. The point light source can be formed without being dispersed, and the point light source preventing unit 80 serves to prevent the point light source from being formed in the upper LED module 40.

The point light source prevention unit 80, which serves as described above, is formed in a cross-sectional shape of a truncated triangular shape in which a lower end is in close contact with the upper surface of the LED module and becomes narrower from the lower part to the upper part, and is upward by the upper LED module 40. The light guide member 81 for scattering light irradiated to the light guide, a triangular groove 82 formed in a triangle inclined downward in the downward direction on the upper surface of the light guide member 81, and is attached to the inside of the triangular groove 82 and the It includes a blocking member 83 for blocking the light passing through the upper end of the light guide member 81.

Since the light guide member 81 has a truncated triangular structure, a portion close to the upper LED module 40, that is, a portion in which a large amount of light is generated is relatively thick and scattered relatively more than a thin portion. The light guide member 81 has a structure in which scattering is substantially uniformly from a lower portion to an upper portion.

The triangular groove 82 serves to provide a space to which the blocking member 83 is attached while allowing light passing through the light guide member 81 to be smoothly transmitted to both outsides thereof.

The blocking member 83 serves to block the formation of the point light source by blocking the light directly irradiated to the upper side from the upper LED module 40.

As described above, the point light source preventing unit 80 scatters light uniformly by the light guiding member 81 in a state in which the formation of the point light source is prevented by the blocking member 83 so that the upper epoxy resin layer 60 is formed. Through this, light is uniformly transmitted, thereby preventing glare caused by the formation of a point light source.

Figure 7 is a step diagram showing a method of manufacturing a three-dimensional character for the signboard according to the present invention.

As shown in the drawing, the method for manufacturing a three-dimensional character for a signboard according to the present invention includes a letter board manufacturing step (S10) for producing a letter board, an internal letter member manufacturing step (S20) for producing an internal letter member, and an external letter member. External character member manufacturing step (S30) to produce, the character member attachment step (S40) for attaching the internal character member and the external character member to the dial, and the upper LED installation to install an LED module inside the internal character member Step S50, and the lower LED installation step (S60) for installing the LED module to the lower surface of the dial.

The dial manufacturing step (S10) is a step of forming a letter board by cutting the metal plate in the shape of a letter, and by cutting the inside of the produced letter board in the same letter shape to form an inner letter hole. This step refers to the step of forming an internal character of the same shape in the inside of the dial through the letter itself of the three-dimensional letters to be manufactured through the dial and the inner letter hole. That is, it is a step of forming the basic frame of the three-dimensional characters.

The internal character member manufacturing step (S20) is a step of producing an internal character member by bending a metal plate in a shape surrounding the lower circumference of the inner character hole. This step is a step of manufacturing the inner character member to be attached to the circumference of the inner character hole with the lower surface of the dial, the inner character member is bent form the metal plate after bending the metal plate by welding It is formed into a frame.

The external character member manufacturing step (S30) is a step of producing an external character member having the same height as the internal character member by bending a metal plate in a shape surrounding the lower circumference of the character plate. This step is to produce the outer character member to be attached to the outer periphery of the lower surface of the dial, wherein the outer character member is formed of a closed letter frame by bending the end of the metal plate by welding.

The character member attaching step (S40) is a step of attaching the inner character member by welding to the lower circumference of the inner character hole to the lower surface of the character plate and attaching the outer character member by welding to the lower circumference of the character plate. In this step, it is more preferable that an adhesive or sealant is injected into and sealed to the contact portion between the dial and the outer letter member while the inner letter member and the outer letter member are attached to the lower surface of the dial by welding. This is to prevent the leakage of the epoxy resin through the outside of the outer character member in the process in which the epoxy resin is injected later.

The upper LED installation step (S50) is to attach a blocking film to the lower surface of the inner character member to close the lower surface of the inner character member and to place the LED module on the upper surface of the shielding film to the inside of the inner character member and opaque inside Filling the color epoxy to harden. This step is a step of forming one front light emitting character block by filling the epoxy resin with the LED module installed inside the internal character member.

The reason for installing the barrier film on the lower surface of the internal character member in this step is that after the epoxy resin is completely cured, the barrier film is removed to open the inner upper and lower sides of the internal character member. It is for allowing an epoxy layer to be formed inside.

In the lower LED installation step (S60), after removing the blocking film, the LED module is disposed on the dial inwardly in the state of placing the dial upside down and inwardly between the internal letter member and the external letter member. It is a step of filling and curing the opaque color epoxy. This step is a step of forming one back-lit character block by filling an epoxy resin with an LED module installed on the lower surface of the dial between the outside of the inner letter member and the inside of the outer letter member.

As described above, the present manufacturing method emits light toward the front of the three-dimensional characters by the upper LED installation step (S50) and the lower LED installation step (S60), and emits light around the dial to its rear surface, thereby improving three-dimensional feeling and visibility. It has a structure.

In the method of manufacturing the three-dimensional character for the signboard, the color epoxy used in the upper LED installation step (S50) and the color epoxy used in the lower LED installation step (S60) have different colors, and the upper LED installation step (S50) In the opaque color epoxy is preferably filled relatively lower than the dial.

This is to significantly improve the visibility of the dial as the letter portion of the inside of the letter board and the outer circumference of the letter board to be emitted back light emitting in different colors, the epoxy resin layer in the upper LED installation step (S50) By forming lower than the dial, the epoxy layer enters the inside of the dial to show a three-dimensional effect of the letter by the epoxy layer.

In the method of manufacturing a three-dimensional character for the signboard, it is preferable to arrange the light guide member on the upper surface of the LED module so as to scatter the light of the LED module before filling the opaque color epoxy in the upper LED installation step (S50). The light guiding member scatters light emitted from the LED module to prevent a point light source formed by the LED module.
